Note: Table 14 is by no means a complete summary of all jurisdictions believed to be using various devices cited. It is simply a notation of those neighborhood traffic control devices observed or reported in the above North American conimunities which comprise the data base for this State-of-the-Art report. Many more North American jurisdictions are believed using some of these devices for neighbbrhood traffic control purposes. Jurisdictions cited above may alsp use other devices not indicated on the table. Some devices indicated above are test installations subsequently removed.

The Offices of Research and Development (R&D) of the Federal Highway Administration (FHWA) are responsible for a broad program of staff and contract research and development and a Federal-aid program, conducted by or through the State highway transportation agencies, that includes the Highway Planning and Research (HP&R) program and the National Cooperative Highway Research Program (NCHRP) managed by the Transportation Research Board. The F6P is a carefully selected group of projects that uses research and development resources to obtain timely solutions to urgent national highway engineering problems.* The diagonal double stripe on the cover of this report represents a highway and is color-coded to identify the FCP category that the report falls under. A red stripe is used for category 1, dark blue for category 2, light blue for category 3, brown for category 4, gray for category 5, green for categories 6 and 7, and an orange stripe identifies category 0.

This category is concerned with the research, development, and implementation of highway construction technology to increase productivity, reduce energy consumption, conserve dwindling resources, and reduce costs while improving the quality and methods of construction. 7. hproved Techmology Maimtemamee for Highway

This category addresses problems in preserving the Nation’ highways and includes activities in s physical maintenance, traffic services, management, and equipment. The goal is to maximize operational efficiency and safety to the traveling public while conserving resources. 0. Other New Studies This category, not included in the seven-volume official statement of the FCP, is concerned with HP&R and NCXRP studies not specifically related to FCP projects. These studies involve R&D support of other FHWA program office research.
